Application ledluly 2i), 1901. i

l t Be it known that LALBERT ENNIs HENDER- SON, oi' the city of Toronto, in the county of i York and Province of Ontario, Canada, have invented certain new' and `usefulA Improvements in Roller-Bearings; vand I hereby declarethe following to be a full, clear, and ex- This invention relates to an antifriction roller-bearing for rotatable shafts mounted tatably mounted upon a stationary shaft or axle; and the object of the invention is to so tically no `friction between the `parts when in justing the `parts relatively to each other to tially, of mounting on `the axle `one or more the inner faces of `which are provided with conical-shaped recesses terminating in comtending throughthe ringparallel with the longitudinal axis of the shaft or -axle 'and opposed to the' centers of their respective conical recesses, a Setof antifriction-rollers for each pair of retaining or bearing rings the ends of which are provided with tapering mandrels terminatingin abruptly conical recesses of the retaining-rin gs, the points of tive openings orbores, so that when the mandrels are contained in the recesses the contact Will not be upon the extreme `point ofthe mandrels, but as nearit as Will render the contact substantial, a series of tie-rods for adjustably holding the retaining or bearing rings together to cause'a collective revolution of the antifriction-rollers'and retaining-rings about the `shaft or axle, abutting shoulders on thefshaft or axle and in the hub for the t inner ends of the sets of antifriction-rollers and adjustable shoulders opposed to the outer ends 0i' the set of antifriction-rollers to preon the shaft or axle and to form a thrustbearing upon the' ends of the rollers, as here- `ol" the "antifriction-rollers.

'ROLLER-BEARING.

Serial No. 69,151. (No model.)

Vinafter more fully set forth, and more particularly pointed out'iu the claims.

In the drawings, Figure 1 is a sectional view of the roller-bearing, showing the relative position of the parts. Figs. 2 and 2 are 55 sectional views of modifications of the roller- `bearing. Fig. 3 is an enlarged view of one Fig. l1 is an enlarged sectional view through one of the bearing or retaining rings. Fig. 5 is an enlarged 6o sectional view ot' the axle and sleeve shown Fig. (5 is a sectional AView of a modification of the bearing or retaining rings and antifriction-rollers, and Fig. 7 is an enlarged View of one ofthe antifriction bearingg 65 rollers and a section of the retaining-rings.

Like letters of reference refer to like parts throughout the specification and drawings.

Although the present specitication and vdrawimgs are restricted to a description and 7o illustration of a roller-bearing for a bicycle or automobile wheel, the same parts and `same construction can be adapted to any other style of a wheel, journal-box, or shaft. In Fig. 2 the axle a is shown to be iitted 75 with sleeves or boxiugs b, prevented frontlin- Ward displacement by abutting flanges c, integrally formed With the axle a at the inner ends of the seats therefor and abutting and projecting slightly beyond the peripheries of 8o vthe sleeves or boxings b. Encircling the axle a; are two sets of bearing or retaining rings d, in the inner faces of which are formed conicalrecesses e, terminating in horizontallydisposed openings or bores f, parallel with 85 the axis 0i` the shaft or axle 01,. Contained between the bearing or retaining rings d are `antifriction-rollers g, having tapering man.-

` the contact substantial, and as the recesses e are of much greater diameters than the ends of the mandrels it follows that there Ioo VICJ will be no contact. other than that near the points. Uniting the retaining or bearing rings are tie-rods j, having the shoulders lo, engaging the inner faces ofv t-he retainingri-ngs, and the usual lscrew-threaded Shanks, which pass through the rings and are fitted with nuts l, engaging the outer faces of the rings. -"By means of the tie-rods and the engaging shoulders and nuts'the rings are held in such relatie-11 to each other that the conical recesses will be in horizontal opposition and the antifriction-rollers will be free from contact with each other and with the tierods. The axle a between the sleeves or boxings b and the ends is screw-threaded, and mounted upon the threaded parts are nuts lm, the inner faces of which are recessed to vprovide flanges o to contact with the ends of the rollers g.

By reference to the drawings it will be Anoticed that the ends of the rollers g are correspondingly recessed, theobject of this construction being to minimize the contactingsurfaces thereof withthose of thenuts m. The' abutting fianges c, engaging the inner ends, and the nutsm, engaging the outer ends of the rollers, hold the rollers in their adjusted position on the sleeves or boxings b. lnclosing the rollers g and the retaining-rings d is the shell p of the hub, theinner faces of theends of which are screw-threaded, and contained in lthe hub-shell p-is a centrally-located lining q, having annular abutting flanges fr, the side faces of which are disposed in substantially the saine plane as the side faces of abutting fianges o. The fianges and adjusting-nuts operating upon the rollers prevent the longitudinaldisplacement of the parts. Contained within the hub-shell are antifriction-linings s, opposed to the antifriction sleeves or boxings b. The antifriction-rollers g engage the sleeves or boxings b and linings s (shown in' Figs. 2 and 2a) during the rotation of the wheel or axle and revolve collectively with the bearing or retaining rings about the shaft or axle, each antifriction-roller during such collective revolution revolving individually on its own axis. Contained in the threaded ends of the hub-shell p are annular nuts t, the inner faces of which ,are iitted with annular flanges u, bearing against the outer ends of the antifriction-rollers g. When assembled in position, the nuts t are alined with the nuts m, and formed in the nuts fm, and f areannular recesses c, in which are contained the adjacent rings d, there being su [icient clearance between the rings and nuts to prevent any contact between them. fFitted in the ends of ythe hub or sleeve p are lock-nuts w, bearing retaining-rings are fitted with tapering mandrelsb', having conical-shaped ends b, while in the ends of the rollers g' are formed conical recesses df', terminating in horizontally-disposed bores d'.

In Fig. 2a the axle is shown to -be provided with an .inclosing sleeve c3, having abutting shoulders o4 to prevent the inward displacement of the annularabutting rings c2, engaging and preventing the inward displacement of the sleeves or boxings b2, which boxings are similar in all respects to the sleeves or boxings b. l

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
